(-6+11)x = 20 can you tell me the answer>?

the answer is 4

Step-by-step explanation:

(_6+11) = 5

5 × 4 = 20

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?
